WASHING MACHL'IZYNE Application filed September 20, 1930, Serial No.483,294, and in Germany July 28, 1930.

This invention relates to a novel washing bell by means of which abetter and at the same time a more rapid washing effect is obtainedwithout thereby detrimentally affecting the fabric of the washing. The

advantages of the novel washing bell consist in that it works with adouble effect. During the movement of the inner body the washingsituated under the washing bell is washed by means of air and at thesame time a further cleaning takes place by means of the small suctioncups, a large number of which are pro-vided on the inner body. Thesemany small specially constructed suction cups in conjunction with theirarrangement possess important advantages. It is thus possible tothoroughly wash the entire surface and every portion of the washingwithin the washing bell. The individual suction cups are in no wayinterconnected.

They are pressed with the wide suction portion separately onto thewashing. Each individual suction cup thus produces a hermetic shuttingoff of that portion of the washing which during the subsequent drawingup intensively flushes the fibres of the washing with the lye and drawsout the dirt. The many separate suction cups are so arranged that theyjointly form a single washing surface which, being continuously in upand down movement, produces a yielding, gentle yet perfect washingeffect.

An embodiment of the invention is illustrated diagrammatically inlongitudinal section by way of example in the accompanying drawing inwhich Fig. 1 shows the washing bell in inoperative position.

Figs. 2 and 3 show the effect of the suction cups during the washingoperation.

According to the invention a thin frame 5 of metal or the like isshiftably arranged in a washing bell 1, 2, which frame is provided witha plurality of separate elastic suction cups 11. These suction cups 11have a wide suction surface 13, a narrow middle portion or neck 14 and awide rear portion 15. Owing to this construction they can easily beinserted in bores or recesses 10 in the frame 5 and are properly guidedin the metal frame so that the suction cups can be brought to actionduring the washing operation. The individual suction cups, inserted inthe frame 5 form together a separate washing surface situated under theframe. On the rear side of the frame 5 catches 16 are provided betweenwhich a rigid plate 17 is arranged which is connected to a handle rod 4.This latter serves for actuating the frame 5.

To facilitate the exchanging of the suction cups the plate 17 isslidably mounted under the catches 16. By lifting the plate 15 thesuction cups are relieved on the rear side of their neck 14. The suctioncups '11 mounted in the frame 5 are operated by means. of the frame 5and the plate 17 so that the interior surface 12 of these cups ispressed completely onto the washing without the cups being able to yieldlaterally. The metal parts may be of thin cross-section in order toreduce the Weight of the washing bell and facilitate manipulation. Thespring 18 mounted on the handle rod 4 facilitates the lifting of thebell and retains the handle rod 4 with the pressure plate 17 7 always inraised position. Thus, the suction cups are not unnecessarily loaded,they can expand and retain their elasticity.

If the bell is operated, the frame 5 is first so depressed by means oftlie'handle rod 4 and pressure plate 17, air and lye being at the sametime forced out of the bell through the washing. As soon as the suctioncups 11 have been pressed onto the washing by the further downwardmovement of the frame 5, the interior portion 12 of the suction cups 11being pressed fiat and completely filling the bell under the frame 5 sothat the lye is pressed directly through the washing. The portion of thewashing situated under the washing bell is, after the above describedtreatment, subjected to a further cleaning effect by the many suctioncups 12 which also act directly on the washing.

This double effect during the upward movement of the bell with pressingeffect according to the invention is repeated amplified during itsupward movement. The individual suction cups 11 owing to their shapeproduce a strong suction effect. During the lifting of the washing bellthe suction cups first become detached in that they return from theirflattened shape into their initial shape. Thus the lye is drawn throughthe washing on the entire washing surface covered by the suction cups.As the frame 5 continues to ascend, a suction effect is produced therebyin the washing bell which again acts on the fabric of the washing andefiects the above described action of the suction cups. effect isproduced by pressing during the downward movement of the washing belland by suction during the upward movement thereof, so that the timerequired for Washing is considerably reduced anda perfect washing effectobtained.

I claim:

1. A washing implement, comprising in combination a washing bell, ametal frame having top and bottom parts and sides connecting the samemovable in said bell, a plurality of separate elastic suction cups insaid frame forming a separate washing surface under said frame, amovable plate within said frame and adapted to engage said suction cups,and a handle engaging said plate to raise and lower said frame in saidbell.

2. A washing implement, comprising, in combination, a washing bell, ametal frame movable in the bell-having top and bottom parts and sidesconnecting the same, a plu rality of separate elastic suction cups insaid frame and forming a separate washing surface below said frame, eachof said elastic suction cups having an intermediate contracted neckportion, there being apertures in said bottom part of said framereceiving the necks of said cups, whereby the latter are detachably heldin position on saidframe, a movable plate within said frame and adaptedto exert pressure upon said frame and suction cups, anda handle on saidplate whereby to raise and lower said frame in said bell.

In testimony whereof I affix my signature.
